Background/Aims:
Aim of this work was to analyze retrospectively two groups of patients who underwent hepatic resection using two different techniques, to determine whether exists a difference in hepatic tolerance and in the early outcome.
Methodology:
We retrospectively analyzed seventy-one patients divided into group 1, treated with kellyclasia and Pringle maneuver, and group 2 treated with a radiofrequency device. The following parameters were analyzed: age; sex; type of disease, number of major/minor resections; total operative time and transection time; number and time of clampings; blood loss; pre- and postoperative transaminases and total bilirubin; length of hospitalization; morbidity and mortality.
Results:
Median total operative time and median hospital stay were similar in both groups but median median blood loss was higher in group 1. ALT levels in group 1 were higher than in group 2. Morbidity and mortality were observed only in group 1.
Conclusions:
Kelly-crush is related to a lower parenchymal tolerance as shown by the higher increase in postoperative alanine aminotransferase levels.
